Title: Techniques d'insertion intelligente d'annonces publicitaires video
Inventor: GOLDMAN PHILLIP Y
IPC: H04H20/00
Filed: 1999-06-14
Abstract: L'invention concerne un système et un procédé de sélection et d'insertion d'annonces publicitaires dans une source de programmation vidéo, à domicile. Un dispositif d'insertion d'annonces (60) d'un système audiovisuel domestique (56) reçoit plusieurs annonces (54) d'une source d'annonces (50). Le dispositif d'insertion d'annonces publicitaires (60) sélectionne une des annonces (59) à afficher (61) pour un spectateur, en fonction de critères de sélection d'annonces combinés aux informations sur le spectateur et sur le système. La programmation vidéo est affichée (61) pour un spectateur alors que le dispositif d'insertion d'annonces (60) surveille la source de programmation (52), à la recherche d'un événement signalant le moment approprié pour l'affichage de l'annonce sélectionnée (59). Au moment approprié, la source de programmation vidéo (52) est interrompue et l'annonce sélectionnée (59) est visualisée (61). La sélection d'annonces publicitaires au niveau domestique permet aux publicitaires de cibler des spectateurs avec un degré de spécificité élevée. Notamment, dans les critères de sélection des annonces on peut tenir compte, par exemple, des données démographiques relatives au foyer, de la situation géographique du foyer et des habitudes de visualisation spécifiques. Ledit procédé consiste éventuellement à surveiller et à consigner la réponse du spectateur aux annonces sélectionnées.

Title: Mobile ip registration in selected inter-pdsn dormant handoff cases in a cdma2000-based cellular telecommunicating network
Inventor: MADOUR LILA
IPC: H04W36/12
Filed: 2001-05-08
Abstract: In a cellular telecommunications network, a method and system for performing dormant hand-off for a dormant Mobile Node (MN) between a source packet zone an a target packet zone, when the MN still has an active A10 and Point-to Point ~ Protocol (PPP) connection in the target packet zone. According to the method, when handed-off, the MN issues an origination request with a Data Ready to Sent (DRS) parameter set to zero for the target Base Station Controller (BSC-T) which responsive to the request further sends an A9-setup-A8 registration request to a target Packet Control Function (PCF-T). The PCF-T then sends an A-11 Registration Request message to a Packet Data Service Node (PDSN-T) of the target packet zone. Responsive to the receipt of the Registration request, the PDSN-T sends an agent advertisement message to the MN and initiates the Mobile IP (MIP) registration procedure, and the MN can register the care-of address information relating to the new serving PDSN, the PDSN-T, with its Home Agent (HA). According to another embodiment, the same method is to be used for performing a hand-off of the dormant MN to the target packet zone, when the MN, before issuing the origination request, demands the activation of a packet data session.

Title: Mitochondrial dna damage as a predictor of coronary atherosclerotic heart disease
Inventor: RUNGE MARSCHALL S
IPC: C12Q1/6883
Filed: 2000-01-14
Abstract: The present invention demonstrates that mitochondrial DNA damage occurs prior to, or simultaneous with, atherosclerotic lesion development, that aortic mitochondrial DNA damage increases with age, and that genotype and diet both influence the level of mitochondrial DNA damage. Hence, the present invention demonstrates that mitochondrial DNA damage occurs early in atherosclerosis, and may be an initiating event in atherogenesis, and provides methods to predict coronary atherosclerotic heart disease based upon the amount of mitochondrial DNA damage.

IPC: A61M60/408
Filed: 2000-03-15
Abstract: An extracardiac pumping system (10) for supplementing the circulation of blood, including the cardiac output, in a patient without any component thereof being connected to the patient's heart. One embodiment and application of the extracardiac system comprises a pump (32) that may be implanted subcutaneously at or about the patient's femoral artery in a minimally-invasive procedure, wherein the pump is powered by a battery (44) and a mechanism for charging the battery extracorporeally, whereby the pump draws blood through an inflow conduit (50) fluidly coupled to the patient's femoral artery via, for example, a subcutaneous anastomosis connection, and discharges blood through an outflow conduit (52) fluidly coupled to a second peripheral artery via, for example, a subcutaneous anastomosis connection. The pump may be operated in continuous flow mode, or in a pulsatile fashion synchronous with the patient's heart, thereby potentially reducing the afterload of the heart.  The conduits (50, 52) can be placed in fluid communication with a multi-lumen catheter (510) for single point application of the system to the patient. If desired, a reservoir (410) may be provided fluidly communicating with the inflow conduit. The system may also comprise a device (402) for maintaining at or near body temperature the blood travelling extracorporeally within the system. If further desired, the present system may be carried directly on the patient with a device (610) that holds at least the pump and is carried by a belt or a shoulder strap.

IPC: G01R15/24
Filed: 2000-07-13
Abstract: A reduced minimum configuration (RMC) fiber optic current sensor (FOCS) is proposed which includes a sensing coil or sensing region, a light source and an optical path arranged between the front output of the light source and the fiber optic sensing coil/region. At least one quarter wave plate is disposed between the optical path and the sensing coil/region for converting linearly polarized light beams into circularly polarized light beams propagating through the sensing coil/region. The circularly polarized light beams propagating through the sensing region experience a differential phase shift caused by a magnetic field or current flowing in a conductor proximate to the sensing coil. A light detector is located at the back output of the light source and produces an output signal in response to return light intensity transmitted through the light source. The return light intensity is a measure of the magnetic field in the sensor coil/region. The magnetic field may be produced by an electric current flowing through a wire, wherein the sensor coil can be wound around the wire. Electronics is described which minimizes effects caused by changes in the environmental conditions.

Title: Airplane landing gear suspension and shock-absorbing device
Inventor: ROGERS BURL A
IPC: B64C25/64
Filed: 2002-04-26
Abstract: A shock absorber that uses polyurethane discs for aircraft landing gear. The discs are maintained under compression. When the aircraft lands or taxis, loads further compress the discs. Unlike bungee cords, however, the discs do not release their energy immediately. Rather, they release the energy slowly, which produces a smoother reaction to loads that eliminates any bounce back of the aircraft.
